Enter your income, what you actually save each month, and your expenses. See your savings rate, your years to financial independence, and how small changes compound into massive timeline differences.
Based on starting from zero net worth, 7% annual return, 4% safe withdrawal rate. Your nearest rate row is highlighted.
A $80,000 gross / $60,000 take-home salary with $2,500/month savings and $2,500/month expenses gives a 50% savings rate. At 7% annual return, this reaches FI in roughly 17 years. Cutting monthly expenses to $2,000 and raising savings to $3,000 lifts the rate to 60% — shaving another 4 years off the timeline.
Your savings rate is the single most powerful lever on your path to financial independence. Unlike income (which also inflates your FI target), a higher savings rate simultaneously reduces the target and increases your monthly investment.
Financial independence is typically defined as a portfolio large enough to sustain your spending indefinitely at a 4% safe withdrawal rate (SWR). That means you need 25× your annual expenses. The calculator uses this definition and solves for the year when your projected portfolio crosses that threshold.
The concept behind the benchmark table was popularised by the personal-finance community: a 50% savings rate historically implies roughly 17 years to FI from zero, a 25% rate implies roughly 32 years, and so on. The non-linear relationship is what makes savings rate so powerful — moving from 10% to 20% saves 14 years; moving from 40% to 50% saves only 5.
Important: figures are nominal (pre-inflation, pre-tax on returns). To see real after-inflation growth, subtract roughly 2–3% from your return assumption. To account for taxes on returns outside a tax-advantaged account, subtract a further 1–2%.
Savings rate is the percentage of your take-home (post-tax) income that you save or invest each month. It is calculated as: monthly savings ÷ (annual take-home ÷ 12) × 100. A higher savings rate both increases what you invest and reduces what you spend — compressing your timeline to financial independence from both ends.
A higher income without a higher savings rate just inflates your FI target — you need 25× more to sustain bigger spending. Savings rate controls both sides: it sets how much you invest AND determines your target (25× annual spending at 4% SWR). Someone saving 50% of a $60k income can reach FI faster than someone saving 10% of $200k.
Conventional financial advice targets 10–15%. The FIRE community typically targets 25–50%. At 50%, historical simulations suggest roughly 17 years from zero net worth to FI. At 25%, roughly 32 years. At 10%, roughly 51 years. Any rate above zero is moving you forward.
Your savings rate determines both your annual investment (growing your portfolio) and your annual expenses (the FI target = 25× annual spending). The higher the savings rate, the faster the portfolio grows AND the lower the target — so years to FI fall sharply as savings rate rises.
No. The chart shows nominal growth before taxes on returns. If you are saving inside a tax-advantaged account (401(k), Roth IRA, ISA, RRSP, Super, etc.) growth is typically tax-free or tax-deferred. Outside one, capital gains and dividend taxes reduce the effective return — model with a rate 1–2% lower.
